exclusive write after read memory access

Question asked by foomanchoo on Dec 16, 2012

for a memory location that is accessed by a single thread, is it allowed to do:


old = load_buffer(global_addr);

store_buffer(new, global_addr); // will be executed before the memory load is finished


and expect old to contain the original value and the memory to contain the new value?
